I was going to suggest filters but was wondering what happens when you
cross regions or cross regionservers? What happens if regionserver A
only has half of the fifth page and you need to go to another server to
get the rest? Its filters will know nought of regionserver A's state?
Thanks,

Why the aversion to filters? Thats how we solve this problem, I have a

2008/6/18 Krzysztof Gałęcki <[EMAIL PROTECTED]>:
I can't cache items on List because of two main reasons:
1. I have to many items to cache them in memory
2. I would also like to use non GUID-based rowIds. In that situation we are
talking about inserting items, not just adding them to the end of table
(list).
I think there should be some method which allows to skip n rows (of course
only in case with no filters)

Hi krzych,
If you really need help fast, come see us on IRC. Details are on the
website.
My solution for your problem would be to cache the results in a List instead
of always scanning the table.

Hi
I have a problem with scanner on HTable object: I have a table with
GUID-based rowId. I would like to display items from this table on pages
(for example 10 items on each page). I'm creating scanner on this table
(without any filters!!), skipping for example 40 items (for 5th page) and
then take next 10 rows and returning them as result. The problem is I have
to manually skip that 40 items. Is there any possibility to skip more than
1
row in some other way?
Regards
krzych
